Not unless they're fresh by: Matt - Pasta Recipes Made Easy
Hi James,
Nope, there is no need to cook your lasagna sheets before popping it all in the oven. The usual cooking time of roughly 20 minutes will be plenty.
That is... unless you have made fresh pasta, in which case they need boiling up to 'al dente' firmness.
Do let me know how you get on with your big dish!
Ciao,
Matt
PS: And since you love lasagna, you might find my pasta cookbook of interest. It has a whole section of easy-to-print lasagna recipes inside and comes supplied with a free exclusive Lasagna 101 guide. Ciao!
